I'm trying to use dtml-tree to create a selective menu of objects based on whether or not the object has an "add_to_menu" property. [...] [rh] - if you append sequence-item it will include your whole method, which presumably is not what you want in your tree. Use id.
Not sure. Supposedly objectValues() returns "actual objects", and I assumed that using sequence-item would be something closer to that. <shrug> The finer points of python are still lost on me, but I'm working on it. You are both right.
In principle, you can use "sequence-item" and get the object. Later, when you use it, you can select whatever you need. However, you used: <dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'])"> The "_[...]" calls "...", if this is callable. Thus, "_['sequence-item']" first returns the object and then calls it, if this is possible. In case of a DTML method, the result would be the rendered body of the method. You can use "_.getitem('sequence-item')" to get the object itself and not the result of calling it. Dieter
